UNITED STATES PATENT OFFICE.

FRED SVVALLOIV AND HENRY YUST, OF SENECA, MISSOURI; SAID SWALLOWVASSIGNOR TO SAID YUST.

FLOUR-SIFTER.

SPECIFICATION forming part of Letters Patent No. 460,493, datedSeptember 29, 1891.

Application filed April 18, 1891.

.To all whom it may concern:

Be it known that we, FRED SWALLOW and HENRY YUST, citizens of the UnitedStates, residing at Seneca, in the county of Newton and StateofMissouri, have invented certain new and useful Improvements inFlour-Sifters; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

Our invention consists in new and useful improvements in flour-sitters,which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective viewof our new and improved flour-sitter. Fig. 2isa vertical sectional viewtaken through the sitter. Fig. 3 illustrates in detail the operatinggearing and connections.

The same numerals of reference indicate corresponding parts in theseveral figures.

Referring to the several parts by their designating-numerals, 1indicates the cylindrical body of our new and improved sifter, near thelower end of which is secured on its inner side the slightly-inclinedflange 2. Just below the flange 2 an annulargroove 3 is pressed orformed in the body 1. In the lower end of the body is mounted thereciprocating sieve, which is formed of wire-cloth, the edges of whichare secured to a metal guide-rim 5, the outer edge of which fits andplays in the annular groove 3, formed in the lower end of the body 1. Onthe side of the cylindrical-body is secured a bearing 6, on which ispivoted the large co -wheel 7, having the small handle 7 for conveniencein revolving it. On the lower part of the bearing 6 is pivoted acog-pinion 8, which is formed with the projecting wrist-pin 8.

9 indicates a connecting rod or wire, one end of which is pivotallymounted on the wrist-pin 8 of the cog-pinion, while its other end ispivotally connected to the outer end of an arm 10, projecting out fromthe sieve through a slot 11 in the lower end of the body 1. It will nowbe seen that as the cog-wheel 7 is revolved by its handle the cog-pinionwill be given a large number of revolutions for-each single revolutionof the drive- Serial No 389,497. (No model.)

wheel '7, and as the pinion is thus revolved it fectively sifting theflour with a motion which closely resembles that given by hand to theordinary flour-sitter. A series of spurs or upwardly-reaching arms 12are erected upon the upper surface of the sieve and are adapted to moveand thoroughly agitate the contents of the sifter and thus producebetter results, as will be readily understood.

It will be seen that our improved floursifter dispenses with therotating agitator commonly used, which by rubbing over the surface ofwire-cloth tends to rub dirt and hard lumps of flour through the sifterand wears out the wire-cloth.

Our invention, while sitting flour very rap- 7o idly, retains all dirtand hard lumps of flour and reciprocates the sieve back and forth withgreat rapidity, instead of revolving an agitator over a fixedsieve-cloth, as in some of the flour-Sifters of this class.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and practicaladvantages of our new and improved floursifter will be readilyunderstood without requiring further description.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

The combination of the body 1, formed near 8 5 its lower end with theannular retaining and bearing groove 3, the wire sieve 4, provided withthe series of upwardly-projecting spurs 12 and having the metalguide-rim 5, movably fitting in said groove 3, and the project- 0 ingarm 10,'the drive-wheel 7, the pinion 8, having the projecting wrist-pin8 and the connecting-rod 9, pivotally connected to said wrist-pin and tothe outer end of the arm 10, substantially as set forth.

In testimony whereof we affix our signatures in presence-of twowitnesses.
